COUPLING FOR WlNDMlLL-PUMPS.

SPECIFICATION forming part of Letters Patent No. 595,484, dated December 14, 1897. Application filed February 11 1897. Serial No. 622,949. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH M. KLOPFEN- STIEN, a citizen of the United States, residing at Leo, in the county of Allen, in the State of Indiana, have invented certain new and useful Improvements in Couplings for Windmill- Pumps; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to improvements in couplings for pumps operated by windmills. The coupling-rods of such pumps are usually and desirably constructed so that they can be detached from the motor at pleasure; and the object of my invention is to provide a simple, inexpensive, and reliable coupling which by means of an operating-lever forming a part of the device can be connected to and disconnected from the pump sucker-rod without the use of a wrench or other tool. I attain this object by the device illustrated in the accompanying drawings, in which Figure l is a front view of-the coupling attached at its upper end to the coupling-rod .of a windmill and at its lower end to the sucker-rod of the pump. Fig. 2 is a side view of Fig. 1, and Fig. 3 is a view of the lower part of Fig.2 with the lower front part of the coupling-slide removed to show the internal construction of the connections. perspective View of a modified form of the operating-lever 5 in Figsnl, 2, and 3, and Fig. 5 is a cross-sectional view of the lower part of Fig. 3 through the line w 00.

Similar numerals refer to similar parts throughout the several views, in which- 1 is a fragmentary section of thelower part of the pump-rod of a windmill, and 2 the upper part of the pump sucker-rod, having a perforation 12. (Shown in Fig.3.) Acouplingslide 3, having integral back and sides, as shown in the cross-section view in Fig. 5, is rigidly secured to the end of the coupling-rod 1 by the bolts 6 and 6 or in any other suitable manner. This slide is open in front to near its lower end, where it has its front part integrally united to the sides, as shown in Fig. 1. In the lower end is a Vertical slotted opening 11 for receiving the sucker-rod 2. To the front and rear of the rod 1 are secured by the bolts 6 and 6 the spring-plates 4 and 4, having at their lower ends the integral or rigidly-attached lateral pins 7 and 7, which are mounted in the perforations in the slide 3, as shown in Fig. 3.

An operating hand-lever 5 is pivotally mounted upon the side of the coupling-slide, which is provided with the arms 9 9, adapted to operate between the slide and the spring pressed plates 4 and 4. WVhen this lever is in its normal position, as shown in Figs 1 and 2, the pins 7 and 7 of the plates will be in engagement with the perforation in the suckerrod, working through opposite perforations in the slide, as seen in Fig. 3.

By throwing the operating-lever to a perpendicular position, as shown in the dotted lines in Fig. 3, the arms 9 and 9 will force the plates 4 to the position shown by the dotted lines in the same figure and thereby release the engagement of the pins 7 and 7 from the sucker-rod. The pump-rod 1, with the attached coupling, will then have a free vertical movement independent ofthe suckerrod, and with a pump-handle of usual construction the pump may be operated independent of the windmill-motor.

It is obvious that by tilting the lever 5 back to its normal position the pins 7, as the coupling moves upon the sucker-rod, will automatically by the pressure of the springplates again engage with the rod and a secure connection be made.

In Fig. 4 is shown a modified form of the operating-lever 5, in which additional arms 10 10 are provided, which are intended to embrace the exterior sides of the plates 4 and 4. By this construction each pair of arms 9 and. 10 embrace one of the plates, and when the lever is in its normal position the arms 10 will securely hold the plates pressed against the slide and prevent any disengagement of the pins from the sucker-rod while in use. One of the arms 10 may be omitted and the same result obtained. I find, however, that in actual practice the additional arms 10 are unnecessary and are preferably omitted.

The particular construction of the coupling-slide and the spring-plates and suckerrod, as described, may be varied without de- IOO parting from the scope of myinvention, which is forming the interlocking detachable engagement of the spring-plates with the suckerrod, substantially in the manner described and shown.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a coupling device for pumps operated by windmills, the combination with the pumprod of a coupling, comprising a hollow metallic piece 3, having an integral back and sides and at its lower end having its front part integrally united to the sides with a vertical slotted opening in the end for receiving the pump-rod; the spring-plates 4, 4, having the lateral pins 7, 7, adapted to engage in the JOSEPH M.
